Built to Series 4250 specifications, it features a variable helix angle ranging from 35 to 38 degrees, which reduces harmonic vibration and improves surface finish at the cut. The single-end, four-flute design with a spiral flute geometry and FIREX coating delivers extended tool life when working ferrous and hard materials. At 0.5 inches in diameter with a 2-inch length of cut and 4.5-inch overall length, this tool fits standard CNC machining centers and manual mills equipped with a 0.5-inch collet or Weldon flat holder.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for machining cast iron, steel, stainless steel, and hard materials in both production and job-shop environments. It is centercutting, allowing plunge entry directly into the workpiece without a pre-drilled pilot hole. The right-hand cut and right-hand flute configuration is standard for conventional vertical and horizontal milling setups. Licensed machinists and CNC programmers in aerospace, tooling, and general metalworking shops are the primary users. The long-series length classification provides added reach for deeper cavities and pockets where standard-length tools cannot access the full feature depth.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix angle from 35 to 38 degrees reduces chatter and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eFIREX coating increases wear resistance and heat tolerance for ferrous and hard-material cuts\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and dimensional stability under high feed rates\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank ensures positive drive retention in end mill holders\u003c\/li\u003e\n\u003cli\u003eLong-series overall length of 4.5 inches extends reach into deep pockets and cavities\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 0.5-inch diameter end mill holders or collet chucks with Weldon flat drive. Primary workpiece materials are cast iron and steel; secondary rated materials include stainless steel and hard materials per material codes K, P, H, M, and S as specified by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop safety procedures. Secure the Weldon flat shank firmly in the holder to the manufacturer-specified engagement depth before tightening set screws. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates tool wear and degrades surface finish. Speeds and feeds should be set according to the workpiece material and machine capability; consult GUHRING cutting data tables for Series 4250 parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle Range\u003c\/strong\u003e: 35 to 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 4250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9042500127000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51735352475954,"sku":"9042500127000","price":228.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/913b67042303736a9eeed6cf0ad4cfa7_3e690a98-90fb-4ffc-9163-f95eee7b15ae.jpg?v=1788772059","url":"https:\/\/voomisupply.com\/products\/guhring-9042500127000-square-end-mill-0-5-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
